Description

  The present invention relates to a dishwasher.

  2. Description of the Related Art A so-called built-in dishwasher installed in a system kitchen is provided with a housing having a washing tank for accommodating and washing dishes and a door for opening and closing the front of the housing. In this type of dishwasher, the door is provided with a front panel having the same design as the system kitchen so that a sense of unity with the system kitchen can be obtained when the housing is closed (for example, Patent Document 1 below). reference).

  An upper frame body is attached to an upper edge of the front panel of the door body, and the upper frame body is provided with a grip portion and an operation portion for a user to grip when opening and closing. On the other hand, in order to improve the sense of unity between the door and the system kitchen, the upper frame is sometimes made relatively small (thin) so as to be inconspicuous.

  The operation unit of the upper frame body is a course button for selecting a desired driving course from among a plurality of driving courses, a reservation button for reserving a driving start time, a drying button for changing a drying driving time, And operation switches such as a start button for starting washing.

  Of these, when operating the course button, it is necessary to clearly inform the user of what has been selected by the operation. Therefore, in general, an LED lamp is illuminated on the character printed portion of each course name. ing. However, in recent years, it has become multifunctional, and a large number of courses (for example, standard, careful, speedy, drying, cleaning in the refrigerator, etc.) can be selected. There has been an inconvenient inconvenience that an area for printing the character of the course name and an area for providing a large number of LED lamps cannot be sufficiently secured.

  Thus, it is conceivable to display course names and the like one by one using a display device such as a dot matrix liquid crystal capable of displaying a character string. When the upper frame is small (thin), the display is small, and the screen of the display is also small. If the display is provided near the operation unit even if the screen is small, the user can easily check the display content of the display at the time of operation.

  However, when the screen of the display is small, it is difficult for a user who is away from the dishwasher to visually recognize the display contents. In addition, the completion of the operation of the operation unit eliminates the need to confirm the screen, and if the display on the display is continued even though the user has left the position near the display, the display may become useless. Therefore, the electric power applied to the display is wasted.

  In view of the above, the present invention provides a display device capable of displaying a character string so that the user can reliably recognize the display content when operating the operation switches, and also prevent an unnecessary display state from being caused. It is another object of the present invention to provide a dishwasher capable of reducing power consumption.

In order to achieve the object, the present invention provides a dishwasher including a housing provided with a washing tank for accommodating and washing dishes and a door body for opening and closing the front surface of the housing. An operation unit provided for the user to operate, a display unit provided adjacent to the operation unit and capable of displaying a character string for displaying predetermined information, and controlling the display content and display form of the display unit Display operation means, wherein the operation unit is provided at a position where the door body is in a concealed state when the door body is closed, and the display control means is such that the door body opens the housing. When information is displayed on the display device, when the operation start operation by the operation unit is performed , the display device is set to the non-display state, and washing of the dishes in the cleaning layer is performed when the operation start operation is performed. And is started by closing the door. To.

  The operation of the operation unit (such as a course selection operation) is performed prior to the operation of the dishwasher. A display corresponding to the operation of the operation unit is performed on the display, and the user can operate the operation unit while checking the display on the display. Since the display is adjacent to the operation unit, even if the display of the display is relatively small, the user can check the display contents without any trouble, and the display is provided on the small (thin) upper frame. Can be.

  Then, when the driving is started, the operation of the operation unit related to the driving has already been completed, so that it is not necessary for the user to check the display contents of the display. Therefore, the display control means sets the display to a non-display state when the operation is started. Thus, unnecessary display on the display can be eliminated, and power consumption can be reduced.

  It is preferable that the display control unit sets the display to a display state according to a predetermined operation of an operation unit. Thereby, the user can reconfirm the operation content on the operation unit, and the usability is good.

  Further, in the dishwasher according to the present invention, when the display control means causes the display to display a plurality of pieces of information using character strings, the information is switched and displayed at predetermined time intervals. According to this, a plurality of pieces of information are switched and displayed on the display, so that much information can be displayed even if the display screen of the display is relatively small.

  Further, in the dishwasher according to the present invention, the display control means scrolls and displays predetermined information by a character string on the display. According to this, since a relatively long character string such as an explanation can be scroll-displayed, a lot of information can be displayed even if the display screen of the display is relatively small.

  An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a dishwasher 1 of the present embodiment is incorporated in a system kitchen 2. On the front surface of the dishwasher 1, a door 3 is provided. The door body 3 includes an upper frame portion 4 that is long along the upper edge, and a rectangular face member 5 provided below the upper frame portion 4.

  The face material 5 is replaceable, and is attached with a color tone and a pattern similar to those of the surface material such as the storage door 2a constituting the system kitchen 2. Thereby, when the dishwasher 1 is incorporated into the system kitchen 2, a sense of unity with surrounding system kitchen components can be obtained.

  As shown in FIG. 2A, the door 3 is provided to open and close the front surface of the housing 6. As shown in FIG. 2B, a cleaning tank 7 whose upper side is open is housed inside the housing 6. The door 3 is integrally connected to the cleaning tank 7. Tableware (not shown) can be taken in and out of the cleaning tank 7 by pulling the cleaning tank 7 through the door 3 toward the front of the housing 6.

  As shown in FIG. 3, the upper frame portion 4 of the door body 3 is formed in the shape of a quadrangular prism which is turned over, and a grip portion 8 is provided at a central portion thereof. The exhaust port 9 is provided. The grip portion 8 is a portion that is gripped by the user when pulling out the cleaning tank 7 from the housing 6. The exhaust port 9 is for discharging the drying air sent into the cleaning tank 7 during the drying operation to the outside of the machine, and communicates with the inside of the cleaning tank 7.

  An operation unit 10 and a display 11 adjacent to the operation unit 10 are provided on the upper surface of the upper frame 4 of the door 3. Further, on the front surface of the upper frame part 4, a state display part 12 for indicating the operation state by lighting of a plurality of display lamps is provided.

  As shown in FIG. 4A, the operation unit 10 includes a plurality of operation buttons (in this embodiment, a start button 10a, a course button 10b, a reservation button 10c, and a drying button 10d). The display 11 has a display screen on which a character string can be displayed by an LCD, an organic EL, or the like.

  In FIG. 4A, for convenience of explanation, all of the operation unit 10, the display unit 11, and the status display unit 12 are shown in a lighting state, but only the necessary ones are turned on by a user's operation or driving control. So that unnecessary items can be turned off. FIG. 4B shows a state in which all of the operation unit 10, the display 11, and the status display unit 12 are turned off by a power-off operation or the like using the start button 10a.

  Then, as shown in FIG. 2A, the operation unit 10 and the display 11 are connected to one of the system kitchen 2 when the door 3 is in the state where the housing 6 is closed (when the washing tank 7 is housed inside the housing 6). The part (front end) is concealed because it covers from above.

  The display 11 displays functions and the like determined by operating the operation unit 10. The display content and display form of the display 11 are controlled by a display control unit (display control means) provided as a function of a controller (not shown) for controlling the operation of the dishwasher 1.

  After the user presses the start button 10a to turn on the power, the display control unit enters a state in which a predetermined display is performed on the screen of the display unit 11. On the other hand, the dishwasher 1 does not start each operation unless the door 3 closes the housing 6. Then, when the power is ON, when the start button 10a is pressed as the operation start operation, the display control unit sets the display 11 to the non-display state. Subsequently, when the door 3 is closed, the operation in the cleaning tank 7 is started.

  As described above, during the operation in which the display on the display 11 becomes unnecessary, the power supply to the display 11 does not need to be performed, so that the power consumption can be reduced.

  Further, when the user is operating each operation button, the current setting items can be displayed in detail on the display 11, so that the setting operation can be performed reliably while checking the display contents of the display 11. The desired settings can be made reliably. Specifically, when the user operates each operation button to select a course, the display contents of the display 11 can be checked, so that mistakes in the course selection and the like can be prevented and the desired course can be reliably selected. Can be. Therefore, it is possible to reliably prevent the user from starting the cleaning without noticing the mistake of selecting the course and failing to perform the cleaning desired by the user.

  Although the operation unit 10 and the display 11 of the present embodiment are arranged on the upper surface of the upper frame 4 of the door 3, the present invention is not limited to this. The operation unit 10 and the display 11 may be provided on the front surface. Also in this case, the power consumption can be reduced by setting the display 11 to the non-display state during operation. At this time, the operation unit 10 and the display 11 arranged on the front surface of the upper frame unit 4 are exposed on the front surface even when the door 3 closes the housing 6. Therefore, for example, even during the cleaning operation, a course display or the like may be performed by energizing the screen of the display 11 in accordance with the operation of the operation unit 10.

  Here, control on display of the display 11 by the display control unit of the controller will be described with reference to the flowchart of FIG.

  First, when the power is turned on in STEP1 by the user pressing the start button 10a, the display control unit of the controller proceeds to STEP2 and performs course display on the screen of the display device 11.

  The course display shows the currently selected course. Each time the course button 10b is pressed, the selected course is switched and displayed. For example, each time the course button 10b is pressed, the display indicating the course name such as "standard", "speedy", "careful", and "inside store" is switched.

  Next, the display control unit of the controller proceeds to STEP 3 and determines whether or not another button (the drying button 10d or the reservation button 10c) has been pressed. If five seconds have elapsed without pressing the other button, the process proceeds to STEP 4. Then, a character string (sentence) explaining the course is scrolled on the screen of the display 11 at a visible speed. Specifically, when 5 seconds have elapsed since the course name "Standard" is displayed on the screen of the display unit 11, the character string "Course to be washed immediately after eating." Is displayed. As described above, by scrolling the character string, much information can be displayed even if the screen of the display 11 is small. Then, the display control unit returns to STEP 2 when the processing of STEP 4 ends.

  On the other hand, when another button (the drying button 10d or the reservation button 10c) is pressed in STEP3, the display control unit proceeds to STEP5, and performs a display corresponding to the pressed button on the screen of the display device 11.

  The drying button 10d is pressed to change the drying time set for each course, and every time the drying button 10d is pressed, for example, 30 minutes from "drying 0 minutes (no drying)" to "drying 4 hours". It is displayed every minute to one hour. The reservation button 10c is pushed to set the time to start driving, and is displayed every hour from, for example, “no reservation” to “after 6 hours” every time the reservation button 10c is pressed.

  Then, the display control unit performs the processing of STEP5, and after 5 seconds have elapsed without any button operation, proceeds to STEP6 and switches to the course display. At this time, each time the course button 10b is pressed, the selected course is switched and displayed. After 5 seconds have elapsed, the process proceeds to STEP4, and the character string (text) describing the course selected in STEP6 is scrolled at a visible speed.

  As described above, since a plurality of pieces of information are switched and displayed on the display 11 every predetermined time (5 seconds in this embodiment), it is possible to display a lot of information even if the screen of the display 11 is relatively small. Can be.

  Further, although not shown, the controller causes the display control unit to display error information on the screen of the display 11 when a failure such as a failure is detected. Specifically, the display control unit displays an error code (for example, “E-17”) on the display 11, and then takes measures against the error indicated by the error code on the display 11 (for example, “repair is required. Please contact your dealer. "). Thus, the user can quickly know the response to the error notification based on the information obtained from the display 11.

  In this embodiment, the display contents of the character strings on the display 11 include the course name, a sentence explaining the course, a time, an error code, and a sentence explaining an error countermeasure, but the present invention is not limited to this. . In addition, as an example of the display mode of the display device 11, switching between the course name display and the scroll display of the text explaining the course is performed every predetermined time (for example, 5 seconds), but the present invention is not limited to this. As another example of a character string, in addition to a sentence or a phrase, a picture (illustration) or figure with a meaning may be displayed. The picture (illustration), the figure, and the character may be simultaneously displayed or mixed. They may be displayed together.
